Patent DE-19729496-A1 (DE)
Title: Heat-exchanger especially for use as serpentine flat tube condenser
Inventor: STAFFA KARL-HEINZ DIPL ING
IPC: F28D1/047
Filed: 1997-07-10
Abstract: The heat exchanger has a tube block (1) formed by serpentine flat tubes (2a-2f) connected in parallel. On each side of the block is a plenum chamber, into which all the tube ends (8a,9a) at the same sides lead. The tube ends are assembled together to form a stack, with their wide sides towards each other and at a distance apart less than their width. These ends are inserted in a baseplate (10,11) so as to form a sealed joint. Each baseplate and a cover enclose the respective plenum chamber. The tube ends can bear against each other in a common opening in the baseplate, or can be inserted in separate openings with ribs between them.

Patent DE-19742184-A1 (DE)
Inventor: NIEDERREITER HANS DIPL ING
IPC: H02M3/02
Filed: 1997-09-24
Abstract: The invention relates to a switched-mode power supply device with a starting circuit. The control devices controlling the switching transistors in the switched-mode power supply devices are provided with a starting voltage by said circuit. The starting voltage is necessary during the starting phase of the power supply devices. Said starting voltage is provided by a start capacitor. According to the invention, a resistor of the starting circuit carries out a dual function. It serves as a series resistor for the starting capacitor while it is being charged with an input voltage. A control voltage is derived from said resistor, which is used as a controlled variable for the control device. The only condition is that the resistor is connected to the input voltage. Component costs for the starting circuit can be reduced in view of the fact that said resistor is able to carry out these two functions.
